Description

Device, transport movers and transport moversystem

The present invention relates to a device for moving objects with a plurality of individually movable by means of Magnetförder- and / or linear motor technology Transportmover for transporting the objects, a web system for the Transportmover in which the Transportmover along at least one predetermined path in a transport direction are movable, and a control device for controlling the movements of the transport movers in the web system, wherein the web system has a guide for the transport movers extending along the web. The present invention also relates to a transport mover for transporting objects having a functional area and a support for carriers for objects to be transported mounted above the functional area. Furthermore, the present invention relates to a transport moversystem.

A device for moving portions which consist of at least one slice of a food product is known from DE 10 2014 104 400 A1. This device comprises a plurality of individually movable transport movers, a transport copier track system in which the transport movers are movable along at least one predetermined path in a transport direction, and control means for controlling the movements of the transport movers in the railway system. The transport movers have a runner interacting with the web system and a carrier attached to the runner via a holder for at least one portion. As a guide serving as angle plates running guide rails, which engage in slots on the left and right side surfaces of the rotor. It is an object of the present invention, in particular with regard to robustness, compactness, cleanability and payload, to provide an improved device for moving objects and an improved transport movers or an improved transport moversystem.

The object is achieved by a device having the features of claim 1 or by a transport movers having the features of claim 5 or by a transport movers system having the features of claim 21. Preferred embodiments and embodiments of the present invention are indicated in the dependent claims.

The object is achieved in particular in that a device for moving objects of the type mentioned is further developed in that at least one rolling or sliding element is arranged on each Transportmover and that the guide receives at least substantially vertical forces on the rolling or sliding element and wherein the guide has at least one running surface for the rolling or sliding element extending along the track.

In the device according to the invention, the guide thus fulfills a double function, since it not only serves as a guide for the transport movers, but also provides the supporting and running surface for the rolling or sliding element. The guide assumes at least substantially vertical forces, so that the roller blind is normally located above the running surface and thus the weight of the Transportmovers is transmitted via the rolling or sliding element at least substantially in the vertical direction on the tread.

The rolling element is preferably a roller and the sliding element is preferably a skid that can roll or slide along the tread. This results in a rolling element no or at most only a low frictional resistance between leadership and movers. Even when using a sliding element, the frictional resistance can be kept low, especially when the sliding element is made of a lubricious material. Abrasion and wear on the tread and / or on the rolling or sliding element can thus be kept low. In addition, the rolling or sliding element can be exchangeably mounted on the mover, so that it can be changed, for example, when worn.

According to a preferred embodiment of the invention, the guide comprises two parallel guide rails, wherein the upper side of a guide rail is provided as a running surface for at least one rolling or sliding element which is arranged on a longitudinal side of a Transportmovers, and wherein the upper side of the other guide rail as a running surface is provided for at least one rolling or sliding element, which is arranged on the other longitudinal side of the Transportmovers. By the two mutually parallel guide rails, rest on the respective upper side of the rolling or sliding elements of the mover and roll or slide, a stable, safe and cost-effective guidance for the movers is created.

According to a preferred embodiment of the invention, each guide rail comprises on its, the other guide rail side facing a projection and each longitudinal side of a Transportmovers comprises a projection, wherein a respective projection engages under a respective projection in arranged on the guide rails Transportmover. The transport mover may thereby be prevented from falling out, e.g. while cornering.

The projection may extend at a distance below the rolling or sliding element, so that an outwardly open gap is formed between the rolling or sliding element and the projection. In this gap, the projection of the associated guide rail can engage. The gap therefore has a width, which corresponds at least to the thickness of the projection or the gap width is slightly larger than the thickness of the projection.

The protrusion can be considered as a lateral sliding guide, which provides with the gap for a correct alignment of the pairs of rollers in cornering and driving straight ahead. The rolling or sliding elements assume in particular the support function, while the sliding guide and the gap mainly take over the guiding function, in particular laterally. The guide rails may be formed, for example, as an angle plates whose respective upper side form the tread for the movers and their free ends are arranged facing each other, so that the free ends of the angle plates form the projections which engage in the column, on the longitudinal sides of the movers are formed.

The invention also relates to a transport movers for transporting objects, in particular with a device according to the invention, the transport movers having a functional area and above the functional area a holder for carriers for objects to be transported attached to the functional area, wherein at least one of the two longitudinal sides of the functional area a rolling or sliding element and at a distance below a projection are provided so that between the rolling or sliding element and the projection an outwardly open gap for the engagement of a projection is provided, which is formed on an associated guide rail for the Transportmover. By engaging the projection in the associated gap, the side guide is improved. The mover can thus be safely and stably guided. In addition, the mover can be prevented from falling up out of the guide, for example during cornering. The rolling or sliding elements are preferably arranged detachably on the functional area. They can therefore be exchanged if necessary, for example if they are damaged or worn or if they are to be adapted to special applications, in particular the payload to be transported.

Preferably, the functional area is integrally formed. Thus, the functional area can be made compact and stable.

The functional area is preferably made of a plastic, so that it can be processed well and produced with a low weight.

Below the functional area, a magnetic area can be provided, which is releasably secured to the functional area. In the magnetic region, the mover-side devices can be accommodated, which are provided in a manner known per se for interacting with the web-side magnetic conveying system. Due to the solvability of the magnetic area of the functional area, these areas can be made independently and, if necessary, also replaced or adapted. According to a preferred development of the invention, the, in particular flat, lower side of the functional region and the, in particular flat, upper side of the magnetic region are at least approximately in contact with each other when the magnetic region is attached to the functional region. The connection between magnetic area and functional area can thus take place via an at least substantially accurately fitting contour, preferably in a horizontal plane.

Preferably, in the edge region between the top and the bottom of a circumferential seal, in particular O-ring seal arranged. As a result, the interior of the magnetic area is sealed from the outside area and protected, for example, against penetrating water or cleaning agent. Thus lies a design of the connection area, which also meets high hygiene requirements.

In particular, it may be provided that the magnetic region is hollow and designed to be open on its upper side. The devices of the magnetic region can therefore be integrated into the magnetic region from the top side. When the magnet area is located at the functional area, the interior of the magnetic area is protected from the outside due to the gasket.

The seal can seal off any gap between the top of the magnet area and the bottom of the functional area. It is preferably offset slightly behind the edge of the magnet region and the functional region. The seal can also serve as a tolerance compensation between the magnetic area and the functional area.

In particular, the seal is at least partially received in a formed on the top and / or bottom, circumferential groove. Through the groove, the seal can be held securely, e.g. during the assembly of the magnetic and functional area. In addition, an improved sealing effect can be achieved.

In the functional area, at least one first channel, in particular a blind hole, can extend vertically upward from the underside of the functional area, and a second channel, in particular horizontally extending, can cut the first channel to accommodate an axis of the transport movers.

In the first channel may be attached to the top of the magnetic region fixed or fixed fastener of the magnetic region, in particular a bolt-like element, such as a mushroom head screw inserted. In the second Channel, the axis can be plugged. The fastening element can be designed in such a way that it engages behind the axis above the region in which the two channels intersect, in order to fix and / or clamp the magnetic region with respect to the functional region. The fastened to the magnetic region fastener engages from below into the first channel and it can be secured via the inserted into the second channel axis.

The axis can be arranged against rotation in the second channel and / or fixed. A rolling or sliding element can be screwed onto one end of the axle. The end can be threaded with it. Due to the rotationally secure arrangement of the axis, co-rotation of the axle is prevented, in particular during the screwing on of the rolling or sliding element and during a movement of the transport movers. Preferably, the rolling element is designed as a roller, in particular a stainless steel bearing with a radially outer raceway, e.g. made of rubber.

The bearing can be screwed onto the thread of the axle. Before screwing on the bearing, a screw can be screwed onto the thread and tightened against the bearing. It is particularly advantageous if the screw has a larger diameter collar and the bearing is provided a complementary receptacle for the federal government, being absorbed by tightening the screw against the bearing of the federal government in the recording. This allows the bearing to be securely fastened to the axle.

The axis can be inserted into the second channel of the functional area. A multi-edge contour provided on the axle can engage in an associated counter-contour on the second channel in order to achieve an anti-rotation lock. The axis is preferably formed of a metal or stainless steel. Also, the fastening means for fixing the magnetic region at the functional area are preferably formed of a metal or stainless steel. The functional area may comprise at least one rolling or sliding element together with mounting, in particular in the form of at least one axis, as well as fastening elements for in particular upwardly directed attachments, such as a holder for a slide. This can be designed as a plate or pot-like.

The holder is preferably connected by means of a rotation axis rotatably connected to the functional area. This is particularly advantageous when a holder is supported by two movers arranged one behind the other, since in comparison with a rigid attachment, the system of two movers and a holder rotatably mounted thereon has a better turnability.

The axis of rotation may be rotatably arranged in a, preferably continuous, channel which extends in the vertical direction in the functional area. Preferably, the axis of rotation is mounted by means of at least one sliding bearing in the channel. For example, a sliding bearing may be provided at an upper end and / or at the lower end of the channel for supporting the axis of rotation with respect to the channel. The slide bearing at the upper end of the channel may have a collar which rests on top of the functional area. The at least one slide bearing can act horizontally and / or vertically and also cause additional damping.

The channel can extend continuously in the vertical direction through the functional area. The axis of rotation can at its lower end face with a

Secure the screw, which is screwed from below into a threaded hole on the lower front side. The axis of rotation may have an upper end face lying above the functional area, which is provided as a bearing surface for the holder. On the front side, a threaded bore may be provided, into which a screw guided from above through an opening in the holder screw is screwed or screwed for securing the holder to the axis of rotation. The holder can thus be fastened by means of the screw to the axis of rotation. Instead of the screw can also be used another fastener.

The aperture on the holder can be formed at least substantially matching the end face of the axis of rotation as a polygonal, in particular square. The functional area may comprise at least one pair of rolling elements, in particular a rear or front pair of rolling elements viewed in the direction of movement of the transport movers, one rolling element of the pair arranged on one longitudinal side of the functional area and the other rolling element of the pair on the other longitudinal side of the functional area is, and wherein the two rolling elements have a common, continuous axis. The two rolling elements are thus seen in the direction of movement of the Transportmovers at the same height, which may be advantageous in particular when driving straight ahead. In addition, a uniform support of the Transportmovers can be achieved by the rolling elements.

According to a preferred embodiment of the invention, the functional area comprises at least one pair of rolling elements, in particular a rear or front pair of rolling elements viewed in the direction of movement of the transport movers, one rolling element of the pair on one longitudinal side of the functional area and the other rolling element of the rolling element Pair on the other long side of the Functional range is arranged, and wherein at least one rolling element relative to the other rolling element along the direction of movement is offset, in particular by about 10 to 30 millimeters. As a result, a better, quieter running behavior, in particular at passages between railway elements, can be achieved. The offset between the rolling elements is in particular such that a transition between rail elements is bridged. The pre-offset rolling element has thus already passed a transition between successive track elements and thus supports the mover, while the other rolling element is in the transition area and may not have any contact with the tread for a short time.

The transport mover preferably comprises a pair of rolling elements which have an offset seen in the direction of movement of the mover, and a further pair of roller elements without offset. The pair without offset is preferably arranged on a common axis.

In the coupling of two transport movers to a transport system, the pairs of rolling elements of the two transport movers, which have no offset, preferably stand together.

It is also possible for all, preferably four, rolling elements of a mover to be arranged in each case on their own axis. In addition, all rolling elements seen in the direction of movement relative to each other have an offset. The offset can vary in size in order to be able to bridge gaps at transitions between web elements.

According to a preferred embodiment of the invention, the Transportmover on each of its longitudinal sides at least two rolling elements arranged offset in the direction of movement, wherein the rolling elements on each longitudinal side via a connecting element with each other and with the respective longitudinal side of the Trans- portmovers are connected, wherein the connecting element is arranged pivotably about a pivot axis on the respective longitudinal side of the Transportmovers. The rolling elements on each side of the Transportmovers can thus be arranged by means of the connecting element in the manner of a pendulum suspension on Transportmover.

The connecting element may have a first portion, one end of which is arranged on the pivot axis and is arranged on the other, free end of one of the rolling elements, and the connecting element may have a second portion, one end of which is arranged on the pivot axis and on the other , Free end, the other of the rolling elements is arranged, wherein the two sections are designed the same or different lengths. Thus, a centrally or eccentrically mounted suspension can be realized. In an off-center suspension, so at different long sections of the connecting element, a different handling of the

Transportmovers be achieved. In particular, depending on the length of the sections, a more or less strong lifting of a transport mode carrier can be achieved after an impact between web elements or the like. Depending on the direction of movement, the position of the pivot axis can contribute to advantageous, uniform movement of the load when driving over bumps.

The pivot axis may have an offset seen on a longitudinal side of the Transportmovers with respect to the pivot axis on the other longitudinal side of the Transportmovers in the direction of movement of the Transportmovers. As a result, a better handling of the Transportmovers can be realized, especially if two such Transportmover are used as Transportmoversystem and are coupled together via a common bracket.

The above explanations also apply to a sliding element, even if only one rolling element is mentioned above. Ie a rolling element can be replaced with a sliding member such as a skid. The axle positions or the mounting points of the rolling elements can be exploited as attachment points for the skids to ensure easy replacement. The skids may be profiled at least on one side serving as a sliding surface. In particular, radii or bevels / chamfers may be provided in the corner area. This allows for easier emergence on transitions and overflow of dirt. The sliding surface may have a slight crown in the longitudinal direction and / or transverse direction. A transverse profiling and / or transverse grooves and / or an oblique contour in the sliding surface can serve as a scraper in order to laterally move impurities away from the web.

In at least one transport movers, at least one elastically deformable bearing can be provided between the holder and the functional area.

Preferably, the storage is designed as skateboard axle, so that when cornering the holder is tilted by means of storage.

For lubrication of the running surface, ie the rolling and sliding surfaces on the guide rails and of moving parts on the mover, in the transport mode, e.g. be provided in its functional area, a lubricant reservoir. The discharge of the lubricant can be done via nozzles.

A sliding element, such as a skid, or a portion thereof, in particular the sliding surface of the sliding element, may be made of a sintered material (metal,

Plastic), which is preferably porous. This can be impregnated with lubricant or it is used for distribution and applied for this purpose with lubricant from a depot in Transportmover. The lubrication may preferably be at the transport mover via the mating surfaces between the mover and the tread. Sintering material, impregnated materials and / or lubricant outlet channels can be provided in the region of the mover-sided contact surface.

For example, the lubricant may be introduced into the mover before, during, or after cleaning, or in a special makeup station (for example, in a side branch of the railroad track). Special transport movers and tools with lubrication function can also only be temporarily in operation on a railway line.

The invention also relates to a Transportmoversystem with at least two successively arranged Transportmovern invention, which have a common support for carriers for objects to be transported, wherein the holder is attached to the functional area of the two Transportmover.

The invention also relates to a transport movers system with two transport movers, which are coupled to one another via a holder such that the distance between the two transport movers is adjustable. A greater distance between the transport movers offers advantages when cornering.

The transport movers may also be other transport movers than the described transport movers with rolling or sliding elements. The aspect of the adjustability of the distance between two coupled transport movers is thus not dependent on the special configuration of the transport movers.

It is advantageous if at least one transport mover and the holder are coupled to one another in such a way that the transport mover moves relative to the holder in transport direction can be adjusted. The axis of rotation of the Transportmovers can be mounted or arranged to be displaceable on the holder.

The transport movers described herein have a wide range of applications. They are flexible, multifunctional and can be used with various bodies. It is a simple parts exchange possible and they are easy to disassemble. They are easy to control or control. They can be designed robust and compact, so that they have a high payload or load capacity with low weight. The transport movers are also designed according to hygienic aspects and are easy to clean. They are suitable for operation in warm, cold, damp and pollution-prone environments, as is often the case in the area of food processing machines. In operation, they have a low frictional resistance in the railway line. They are easy to manufacture, especially if the functional area is made of plastic.

FIG. 22 shows a top view of a web system and a transport movers system with a variable distance between two transport movers. FIG.

The device 1 shown in Fig. 1 1 is provided for moving objects, which are stored on the top of plate-like carriers 13. By way of example, the objects may be portions which in each case comprise at least one slice separated from a food product, in particular by means of a high-speed slicer.

The carriers 13 are placed on a holder 15 or fixed therein, wherein a holder 15 can receive two transversely juxtaposed to the transport direction T carrier 13. In each case a holder 15 is supported by two along the transport direction T successively arranged Transportmovern 17. Such an arrangement of two transport movers 17 one behind the other, which have a common holder 15, is also referred to herein as a transport movers system 19. Examples of such Transportmoversystenne 19 are shown in Figs. 2 and 3 in a perspective view. In the illustration of FIG. 1, two transport system lines are arranged one behind the other as seen in the transport direction T. The transport direction T corresponds to the direction of movement of the transport movers.

The device 1 1 of FIG. 1 comprises a web system 21, which is shown only in sections in FIG. 1. In the web system 21, the transport movers 17 are movable along a predetermined path. The transport or movement direction T of the transport movers 17 is thus predetermined by the web system 21.

The movement of the transport movers 17 in the web system 21 takes place by means of a magnetic conveying and / or linear motor technology, which is known per se. In the illustrated system with essentially vertically acting magnetic forces between the linear motor of the web system 21 and the magnetic region 41 of a transport movers 17, the invention also encompasses drives with a horizontal effect of magnetic forces as the drive system. For controlling the movements of the transport movers 17 in the web system 21, the device 11 has a control device (not shown). The controller and the process of controlling the transport movers 17 along the path are known per se.

The web system 21 has a guide 23 for guiding the transport movers 17 along the track, which guide is formed by two parallel guide rails 25 in the variant shown in FIG. At least one rolling element 27 (see Fig. 3) or at least one sliding element 29 (see Fig. 2) is arranged on each longitudinal side of a transport movers 17. In particular, on each longitudinal side of the transport movers 17 of FIG. 2, a sliding element 29 designed as a skid is arranged. On the other hand, the transport movers 17 of FIG. 3 has two rolling elements 27 designed as rollers on each longitudinal side. The respective rolling or sliding element 27, 29 rests on the upper side 31 of one of the guide rails 25 and rolls or slides on this upper side 31, when the Transportmover 17 moves along the transport direction T. The guide rails 25 therefore absorb mainly vertical forces via the rolling or sliding elements 27, 29 arranged thereon and provide a running surface (surfaces 31) for the rolling or sliding elements 27, 29.

As shown in FIG. 1, each guide rail 25 is formed as an angle plate. The upper, free ends of the angle plates face each other. The free ends of each angle plate form a respective projection 33 which engages under a formed on each longitudinal side of a Transportmovers 17 projection 35 when the Transportmover is arranged with its rolling or sliding elements 27, 29 on the guide rails 25. The projection 35 is arranged at a distance below the rolling or sliding elements 27, 29, so that an outwardly open gap 37 is formed between the rolling or sliding elements 27, 29 and the projection 35 (see also FIG. 6b). , In this gap engages the respective projection 33, whereby the Transportmover 17 is secured against falling out.

The width of the gap 37 - measured from the underside of the rolling or sliding elements 27, 29 to the top of the projection 35 - is preferably chosen so that it is slightly, for example a few millimeters, greater than the thickness of the projection 33 and the free End of the guide rail 25 forming an angle plate.

The transport movers 17 has, in addition to a so-called functional area 39, a magnetic area 41 attached to the functional area 39. As shown in FIGS. 2 to 4, the holder 15 is located above the functional area 41, on which the holder 15 is mounted. The magnet area 41 is located In contrast, below the functional area 39. On each of the two longitudinal sides of the functional area 39, the rolling or sliding elements 27, 29 are arranged and at a distance below a respective projection 35 is formed so that the outwardly open gap 37 on each longitudinal side of the Transportmovers 17th is formed in the region of the functional region 39.

The functional region 39 is preferably formed in one piece, for example made of plastic, and has a flat underside against which the likewise flat upper side of the magnetic region 41 abuts. In the edge region between the upper side and the underside of the two regions 39, 41 is a circumferential O-ring

Seal 43 is provided, which is preferably received in a formed on the top and / or bottom, circumferential groove. The seal 43 seals the gap of the interface between the functional area 39 and the magnet area 41 all around. The seal 43 is preferably offset slightly behind the outside of the functional area 39 or the magnetic area 41 inwards. The seal 43 can also serve as tolerance compensation between the functional area 39 and the magnetic area 41.

As shown in FIGS. 4 and 5, in the functional region 39, two first channels 45, which are formed in the form of a blind bore, are formed which extend vertically upwards from the underside of the functional region 39. Each first channel 45 is cut by a horizontally extending second channel 47 passing through the functional area 39. Each second channel 47 is provided for receiving an axle 49 for the rolling or sliding elements 27, 29 of the Transportmovers 17.

In each first channel 45 a trained as a mushroom screw fastener 51 is inserted, which is fixed to the top of the magnetic portion 41 by being screwed into a provided on the upper side of the magnetic portion 41 thread. The fastening element 51 has, at a distance from the upper side of the magnetic region 41, which corresponds essentially to the distance of the second channel 47 from the upper side of the magnetic region 41, a recess which is complementary to the axis 49. When the axle 49 is inserted in the second channel 47, engages the upper, free end of the fastener 51, the axis 49 above the area in which the two channels 45, 47 intersect. This results in a fixation or a tension of the magnetic region 41 relative to the functional region 39. Thus, a secure connection between the functional region 39 and the magnetic region 41 is realized.

Each axle 49 is preferably formed of stainless steel. Each axis 49 is arranged against rotation in the respective second channel 47. A central extension 53 can be provided on each rolling element 27, which has an external thread, so that the extension 53 can be screwed into an internal thread on the axle 49 in order to fasten a respective rolling element 27 to the axle (compare Fig. 6b). , Each rolling element 27 may have a bearing 55 coupled to the extension 53, for example made of stainless steel, and a radially outer race 57.

A sliding element 29 can be fixed by means of screws 59 on the functional region 39, wherein - comparable to a rolling element 27 - each screw 59 can be screwed into an internal thread of an axle 49 (the screws 59 are shown in Fig. 2).

The holder 15 is rotatably connected to the functional region 39 by means of a rotation axis 61. In this case, the axis of rotation 61 is rotatably arranged in a further channel 63, which extends in the vertical direction within the functional area 39 (see FIG. 5). For rotatable mounting of the axis of rotation 61 on the functional area 39, a sliding bearing 65 may be provided at the upper end of the channel 63. This may have a collar which rests on the upper side of the functional region 39, whereby the sliding bearing 65 is fixed in its position in the channel 63. The sliding bearing 65 can act horizontally and / or vertically.

It can also be provided in the lower region of the channel 63, a further sliding bearing 73 which can also act horizontally and / or vertically and which ensures the rotational movement of the axis of rotation 61 relative to the functional region 39. By or the plain bearings 65, 73, a damping effect can also be achieved.

As FIG. 5 shows, the axis of rotation 61 protrudes beyond the functional area 39 and on its upper side has an end face which serves as a bearing surface for the holder 15 (see FIG. 4). On the front side of the axis of rotation 61, a threaded bore 67 is provided, in which for securing the holder 15 is inserted from above through an opening 69 in the holder 15

Screw 71 is screwed. The aperture 69 may be formed at least substantially to match the end face of the axis of rotation 61 as a square or polygonal.

By realized via the axis of rotation 61 connection between the functional area 39 and holder 15, a rotational mobility of the holder 15 with respect to the Transportmover 17 is ensured, which is particularly advantageous if the Transportmover - as Figs. 2 and 3 show - as a pair of two for carrying a holder 15 are used. In particular, the rotational mobility brings in comparison to a rigid arrangement of the bracket 15 on the Transportmovern 17 advantages when cornering. As shown in FIGS. 4 and 5, the axis of rotation 61 is secured to the underside with a screw 75 engaging from below at the front.

As an alternative to the upper plain bearing 65 with collar and / or to the lower sliding bearing 73, which may also include a collar, plain bearings without collar can be provided.

The rolling element 27 shown in Fig. 7a shows two examples of trained on the outer periphery of the movable part of a bearing 55 and / or arranged races, preferably made of rubber. As shown in the upper partial section of Fig. 7a, such a raceway 75 may have an approximately rectangular cross section and be arranged in an associated groove on the outer circumference of the movable part of the bearing 55. Alternatively, as shown in the lower partial section of FIG. 7a, a raceway 77 having a circular cross-section may be used, which may likewise be arranged in an associated groove on the outer circumference of the movable part of the bearing 55. As shown in FIG. 7b, a surface-shaped race 79 or a coating can also be provided on the outer circumference of the movable part of the bearing 55. In the transport movers 17 shown in FIGS. 3 to 6, two rolling elements 27, which are located on different longitudinal sides of the functional area 39, are arranged on one axle 49.

In the case of the transport movers system 19 illustrated in FIG. 8, each of the two transport movers 17 coupled to one another via the common holder 15 has a common axis 81 for two rolling elements 27. On each longitudinal side of each mover 17 is also still a rolling element 27 is arranged with its own axis 83. In this case, the axes 83 for only one rolling element 27 seen in the transport direction T on an offset, which may for example be in the range between 10 and 30 mm. The RoN elements 27 of the two transport movers 17, which have a common axis 81, are in the Transportmoversystem 19 of FIG. 8 together. The rolling elements 27 with offset form in the Transportmoversystem 19 shown in FIG. 8 seen in the transport direction T front and rear roller element pair. The staggered arrangement of the rolling elements 27 offers advantages in the bridging of web elements of the web system 21.

In the transport movers 17 of FIG. 9, each rolling element 27 has its own axis 83. The axes 83 are seen offset in the transport direction T to each other. At this time, as shown in Fig. 9, the distance between the axles 83 of the rear roller element pair may be different from the distance of the axles 83 of the front roller element pair. This makes it particularly well bridges gaps between rail elements at all points of a Transportmovers 17 bridge. All transport movers 17, whether for use as single movers or coupled to a transport movers 19 as double movers, may be unitarily configured with this construction and used, for example, in the web system 21 of FIG. In the transport movers system 19 of FIG. 10, which is shown schematically in a side view, each transport movers 17 has on each longitudinal side two rolling elements 27 which are arranged offset in the direction of movement T. The rolling elements 27 on each longitudinal side are rigidly connected to each other via a connecting element 87 and to the respective longitudinal side of the transport movers 17 or to its functional area (not shown). The rolling elements 27 are arranged at the free ends 85 of the rod-shaped connecting element 87.

In a modified variant, the rolling elements 27 can be arranged on both longitudinal sides of the transport movers 17 on the same connecting element 87, which then substantially covers the functional area of the transport movers 17 forms and on which, as shown schematically in Fig. 10, also the holder 15 may be arranged.

In the transport system of FIG. 11, each transport movers 17 has on each of its longitudinal sides at least two rolling elements 27 arranged offset in the direction of movement T, which on each longitudinal side via the connecting element 87 with each other and with the respective longitudinal side of the transport movers 17 or the functional area are connected. The connecting element 87 is arranged by means of a pivot bearing 91 about a pivot axis S pivotally mounted on the respective longitudinal side of the Transportmovers 17. Thus, the rolling elements 27 are arranged in the manner of a pendulum suspension on the respective longitudinal side of the Transportmovers 17, whereby the Transportmover 17 and the Transportmoversystem 19 can achieve better handling characteristics. The connecting element 87 comprises a first section 87a, one end of which is arranged on the pivot axis S and is arranged on the other, free end 85 of one of the rolling elements 27. The connecting element 87 furthermore comprises a second section 87b, one end of which is arranged on the pivot axis S and on whose other, free end 85 the other of the roller elements 27 is arranged. In the variant illustrated in FIG. 11, the sections 87a, 87b of the connecting element 85 are at least approximately the same length. On the other hand, in Figs. 12a and 12b, modifications are shown in which the sections 87a, 87b have different lengths. It is thus possible to achieve a central mounting of the rolling elements 27 (cf., Fig. 11) or an eccentric mounting of the rolling elements 27 (cf., Fig. 12). An off-center storage causes a changed handling of the Transportmovers 17 and can be advantageous to the handling of the Transportmovers 17, for example, in a collision with a slide, affect. 13 shows a schematic representation of a transport movers system 19 with two transport movers 17 coupled to one another in a plan view. In each transport movers 17, the pivot axis S is arranged offset on a longitudinal side with respect to the pivot axis S on the other longitudinal side of the transport movers 17 in the direction of movement T. As a result, the drivability of the Transportmoversystems 19 can be improved.

A wheel set on one side may be preferred to a transport movers 17 slightly outwards relative to the other. For example, in the transport system 19 of FIG. 13-in relation to the drawn transport direction T-the right, rear rolling element 27 (27a) of the rear transport movers 17 can be pulled somewhat farther back. In addition, the left front rolling element 27 (27b) of the front transport movers 17 may be pulled slightly forward. As a result, the driveability of the Transportmoversystems 19 can be further improved.

Instead of the rolling elements 27 and sliding elements 29 can be used, as they are shown by way of example in FIGS. 14 to 17. In particular, as shown in FIG. 14, a sliding element 29 may have two apertures 93, for example in the form of a respective bore, whose spacing from one another is selected such that they can be fastened to the axles 49 of a transport moss 17 with the above-mentioned screws 59 (see Fig. 2). For damping, an elastic bushing or an O-ring can be inserted into each opening 93.

In order to be able to suspend a sliding element 29, a central (see Fig. 15a) or slightly off-center (see Fig. 15b) opening 93 may be provided in the sliding element 29. In the opening 93, for example, the pivot bearing 91 (cf., Fig. 1 1) are received. 16 and 17 each show a Transportmoversystem 19 with sliding elements 29. The Transportmoversystem shown in FIG. 17 in this case has a pendulum suspension, in which each slider 29 includes only one opening 93 for the pendulum suspension. In contrast, in FIG. 16, the sliding elements 29 are rigidly coupled to the transport movers 17.

FIG. 18 shows a skateboard axle 95 that can be arranged on the functional area 39 in the case of at least one transport movers 17 between the holder 15 and the functional area 39 for the elastic support of the holder 15. When cornering can - like a skateboard - the bracket 15 are thus inclined. Starting from the axis, the central elastic region is then deformed in such a way that the functional region 39 likewise fixed thereto is somewhat entangled or inclined. In the case of a transport system with two transport movers 17, which are coupled via the holder 15, this can have a favorable effect on the cornering behavior.

As mentioned above, it is provided that in a transport moversystem 19 two transport movers 17 are coupled together via the holder 15. As FIG. 19a shows, an elastic and / or rotationally movable coupling of two transport movers 17 can also take place via an articulated rod 97, which is preferably coupled to the functional area of the transport movers 17.

An elastic and / or rotationally movable coupling of the two transport movers 17 can alternatively be achieved via a hinge 99 (FIG. 19b) or a film hinge 101 (FIG. 19c). The hinge 99 or the film hinge 101 are preferably also coupled to the functional area of each transport movers 17. FIGS. 20 and 21 show two elastically formed sliding elements 29 in a side view. Especially when driving over joints between adjacent guides can be achieved with such sliding elements 29 better damping and a more uniform movement of the transport movers 17. Noise and influences on the payload can also be optimized.

The sliding element 29 of FIG. 20 is designed elastically by its shape, in particular in its lower region, which is assigned to the guide rail. In particular, the sliding element 29 in addition to bevels or radii at the end / corner regions on two projections 103 which protrude from a central region 105 forth. By means of the projections 103, it is possible to insert them easily, for example when crossing over connection points. In the sliding element 29 of FIG. 21, the openings 93 may be provided on elastic arms 107, whereby the sliding element is yielding in particular in the area of the bearing. As also shown in FIG. 21, the sliding element 2 has elastic lower end / corner regions 109 and elastic upper end / corner regions 1 1 1 facing the structure.

FIG. 22 shows a plan view of a web system 21 with a transport movers system arranged thereon, consisting of two transport movers 17 which are coupled to one another via a holder 15. In this case, the transportation mover 19 located in the transport direction T for illustration purposes is shown twice. In this variant, the transport movers 17 are arranged along the transport direction T adjustable on the holder 15, whereby the distance between the two Transportmovern 17 can be adjusted. This can be achieved, for example, by the rotational axis (cf., the axis of rotation 61) of the respective transport movers 17 being displaceably mounted or arranged on the holder 15 is. In the holder 15, for example, a guide can be provided, along which the axis of rotation can be adjusted in the transport direction T.

The adjustability of the distance between the two transport movers 17 is particularly advantageous during cornering. When the transport movers 17 are at a greater distance, a support located on the support 15 moves to a smaller, inner radius that is less than the railroad track radius. This reduces centrifugal forces. In addition, the cornering speed can be reduced. After passing through a curve, the distance between the transport screens 17 can be reduced again or adjusted to a normal value.
